(2) Subtropical high? Hot and rainy? Meiyu? It's raining.

Cold and warm air are evenly matched, and the frontal rain belt formed by them lingers in the Yangtze River basin for a long time.

(3) the difference of thermal properties between land and sea.

(4) Landing in the southeast coast in April and May every year, when the Pearl River system in China enters the flood season; In June, the summer monsoon extended westward and moved northward, and the middle and lower reaches of the Yangtze River entered the rainy season (Meiyu period); In July and August, the summer monsoon continued northward, and North China and Northeast China entered the rainy season. At this time, the middle and lower reaches of the Yangtze River are controlled by the subtropical high ridge in the western Pacific Ocean, resulting in dry weather in summer. September: The cold high in the north moves southward, the summer monsoon recedes to the south of the Yangtze River, and disappears in the mainland in 10. Therefore, affected by the summer monsoon, the southern part of China starts early and ends late, so the rainy season is long and there is much precipitation. Affected by the summer monsoon, northern China started late and ended early, so the rainy season is short and there is little precipitation.
